A HELOC will lower your credit score when you open it, but the damage is temporary

Yes, a home equity line of credit (HELOC) affects your credit score. When you apply, the lender runs a hard inquiry, which typically drops your score by 5 to 10 points. Opening the account itself adds a new line of credit to your report. Over time, how you use the HELOC — whether you borrow money, how much you owe, and whether you pay on time — determines whether your score recovers and climbs back up, or stays depressed.

The initial hit is temporary. Most people see their score rebound within a few months if they don't max out the credit line or miss payments. But if you draw heavily on the HELOC and carry a high balance, your credit utilization ratio climbs, and your score can stay lower for as long as that balance remains high.

Key Takeaways

  • A hard inquiry when you apply for a HELOC typically lowers your score by 5 to 10 points, and this effect fades within a few months.
  • Opening a new HELOC adds a new account to your credit mix, which can lower your score slightly but also shows lenders you can manage multiple credit types.
  • Borrowing against your HELOC increases your credit utilization ratio — the amount of available credit you are using — and a high ratio can keep your score depressed.
  • Paying your HELOC bill on time every month helps your score recover and climb back up, because payment history is the largest factor in credit scoring.
  • If you open a HELOC but never draw on it, the score impact is smaller and shorter-lived than if you borrow and carry a balance.

How the hard inquiry affects your score immediately

When you submit a HELOC application, the lender requests your credit report from one or more of the three major credit bureaus — Equifax, Experian, or TransUnion. This request is called a hard inquiry (or hard pull). It appears on your credit report and counts against your score.

The typical drop is 5 to 10 points, though some people see a larger dip if their score is already low or if they have few accounts. The inquiry stays on your report for two years, but its impact on your score fades after about three to six months. Multiple inquiries within 14 to 45 days (depending on the scoring model) usually count as a single inquiry, so shopping around for the best HELOC rate in a short window does not multiply the damage.

Why opening a new account changes your score

Once the lender approves your HELOC, they report the new account to the credit bureaus. This new account affects your score in two ways. First, it lowers your average account age — if you have had credit for 10 years and suddenly add a brand-new account, your average age drops. Older accounts are weighted more heavily, so this can lower your score by a few points.

Second, a new account shows up in your credit mix — the variety of credit types you hold (credit cards, installment loans, mortgages, lines of credit). Having a HELOC alongside other credit types can actually help your score over time, because lenders like to see that you can manage different kinds of debt responsibly. But the initial addition of a new account still causes a small dip.

How borrowing against the HELOC affects your utilization ratio

Your credit utilization ratio is the percentage of your available credit that you are currently using. If you have a HELOC with a $100,000 limit and you borrow $30,000, your utilization on that account is 30 percent. Credit utilization is the second-largest factor in credit scoring (after payment history), and it accounts for roughly 30 percent of your score.

Most scoring models favor utilization below 30 percent. If you draw heavily on your HELOC and push your utilization above 50 percent, your score can drop significantly and stay low until you pay down the balance. This is why opening a HELOC and immediately borrowing a large amount can cause a bigger score hit than opening one and leaving it unused.

The good news is that utilization is calculated month to month. As soon as you pay down the balance, your utilization drops and your score can climb back up — sometimes within a single billing cycle.

Payment history and long-term score recovery

Once you start using your HELOC, the most important factor for your credit score is whether you pay the bill on time. Payment history makes up 35 percent of your credit score. A single late payment can drop your score by 100 points or more, and it stays on your report for seven years.

If you make every payment on time and keep your balance low relative to your credit limit, your score will recover from the initial hard inquiry and new account dip within a few months. Over time, the HELOC becomes an asset to your score — it shows lenders that you can borrow large amounts and manage the debt responsibly.

If you miss a payment or let your balance grow too high, the score damage compounds. Late payments are reported to the bureaus and stay visible for seven years, and high utilization keeps your score suppressed for as long as the balance remains high.

Comparing the score impact of a HELOC to other credit products

A HELOC affects your score similarly to a credit card or personal loan, but with some differences. All three involve a hard inquiry and a new account. The main difference is that a HELOC is a revolving line of credit — you can borrow, repay, and borrow again without reapplying. A personal loan is installment credit — you borrow a lump sum and repay it in fixed monthly payments.

Installment loans typically have less impact on your utilization ratio because they are not scored the same way as revolving credit. A HELOC, like a credit card, is scored based on how much of your available limit you are using at any given time. If you borrow $30,000 on a $100,000 HELOC, that 30 percent utilization counts against you. If you borrow $30,000 on a personal loan, there is no utilization ratio — you owe $30,000 and you pay it back in installments.

A mortgage also involves a hard inquiry and a new account, but mortgages are weighted differently in credit scoring models because they are secured by real estate and considered lower-risk debt.

What you can do to minimize the score impact

If you are concerned about the effect on your score, you have a few options. First, only apply for a HELOC when you actually need to borrow — do not open one just to have it available. The hard inquiry and new account will lower your score whether you use it or not.

Second, if you do open a HELOC, avoid drawing on it immediately or drawing large amounts. The longer you wait to borrow, the more time the hard inquiry has to fade from your report. If you must borrow, keep your balance as low as possible relative to your credit limit.

Third, make sure you can pay the HELOC bill on time every month. A single late payment will erase months of score recovery. Set up automatic payments if that helps you stay on track.

Finally, do not close other credit accounts to offset the new HELOC. Closing an old account lowers your average account age and reduces your total available credit, both of which can hurt your score more than opening the HELOC did.

Frequently Asked Questions

How long does it take for my credit score to recover after I open a HELOC?

The hard inquiry typically stops affecting your score after three to six months. If you do not borrow against the HELOC, your score usually bounces back to its pre-application level within that window. If you borrow and carry a balance, recovery depends on how much you owe — the higher your utilization, the longer your score stays depressed.

Will my credit score go up if I open a HELOC and never use it?

Not immediately. The new account and hard inquiry will lower your score slightly. Over time, if you keep the account open and in good standing, it can help your score by showing lenders you have access to credit and are not using it — a sign of financial responsibility. But the benefit takes months or years to materialize.

Can I improve my credit score by paying down my HELOC balance?

Yes. As soon as you pay down the balance, your utilization ratio drops and your score can climb back up. The improvement can happen within a single billing cycle. Payment history is also crucial — making on-time payments every month is the fastest way to rebuild your score after a HELOC-related dip.

Does shopping around for HELOC rates hurt my credit score more?

No. Multiple hard inquiries from different lenders within 14 to 45 days (depending on the scoring model) typically count as a single inquiry. Shopping around for the best rate is normal and does not multiply the score damage. Just do your rate shopping within a short window to keep inquiries grouped together.

What if I already have a low credit score — will a HELOC hurt it more?

A hard inquiry can have a larger impact on a lower score than on a higher one, but the effect is temporary. The bigger risk is that if your score is already low, you may not may have access to for a HELOC, or you may face a higher interest rate. If you do get approved, focus on making on-time payments and keeping your balance low to help your score recover.
